Question

Consider a driven damped mechanical oscillator is in resonance. Which of the following statements is true?

• A. Driving frequency is twice the natural frequency of the oscillator
• B. Power transfer from the driving source to system is minimum
• C. Driving frequency is the same as the natural frequency of the oscillator
• D. The force damping the oscillations are at a minimum value
• E. The driving force is in phase with the displacement

Hint:

To remember resonance: Think of it as the "sweet spot" where the system naturally wants to vibrate. When you push a swing at its natural frequency, you get the biggest movement with the least effort because energy transfer is maximized.

Answer 1

The Correct Option is C
